Top right, again, does evoke some interest. The other three are just generic and don’t hold my interest. That’s just me though. I’m a sci-fi nerd from way back and seen too much cover art. 

 Left 2 characters look very spec ops, Asian chick looks business or diplomacy or something, old man looks like a modern generic businessman villain (not that that's automatically bad)

they seem like fine characters but usually a movie poster also conveys something about the setting or action, eg A New Hope poster has ships shooting lasers and explosions, plus the characters are in action poses

just seeing your 4 characters doesn't convey who is good or bad or what sorts of things they're going to do in the film / book

another good point of comparison are the frazetta covers, where you usually have 1-2 characters shown in good detail, and some suggestion of action but you don't get the full core of the cast like the Star Wars poster

The most important prop for warriors is a weapon, usually held ready or actively in use. The male warrior seems to have a plate carrier so perhaps he should have a rifle, while the scar on the female warrior suggests close combat - perhaps she should have a blade.

If one or more of those characters is primarily characterized by wealth they should have some indicators of that wealth - such as gold jewelry, cigars, finely tailored clothing, etc.

TLDR: Not enough information to respond to your question 

 Fair.

Part of the OP is a joke. It’s just four of the main character portrait drafts in AI in a quadrant, not an *actual* trailer of any substance. It’s just that when you put four characters together it looks a bit like a trailer, was kind of my joke.

Mainly interested to see vibes of how people feel about each one visually, ignoring the fact that they’re obvious AI for the most part.
